$result=@mysql_query($concatsql, $connection) or die (mysql_error() . "

When building complex queries like this, it's really easy to miss a missing
quote or extra comma, etc. Displaying the query string usually makes it
quite obvious where the problem lies (especially when coupled with a MySQL
error message, since MySQL is pretty good about pointing out the spot where
the syntax fails).
